What is the answers to -7 ( a + b - 5 ) + 8 ( -3a +2b ) + b ( 7 + 3 )
-2
6a-3
3a - 1 = ? relation between a & 3 is ( 3 multiplied by a ) since a = 8, then, 3 * 8 = 24 therefore : (3*8)-1=23
4a - 5 = 7a - 7 -5 = 3a - 7 2 = 3a a = 3/2
-8a + 3a = (-8 + 3)a = (5)a = 5a
What is the answers to -7 ( a + b - 5 ) + 8 ( -3a +2b ) + b ( 7 + 3 )
(3a-8) + 5x(a)
3a + a = 4a Example: a = 5 (3x5) + 5 = 15 + 5 = 20 = 4 x 5
5a times 3a minus 8a = (5*3)*a2 - 8a = 15a2 - 8a
If 3a+5=5a+3, then: 3a+5 - 3a = 5a+3 - 3a 5=2a+3 5 - 3=2a+3 - 3 2=2a a=1
3a - 5 cannot be factored further.
-3a-12 = 12+12 +12-3a = +12~ ~-3 -3a = -8
y = (3 X 8) - 5 = 21.
